Mattak, OK here is a dumb idea. Build a LCR Enclosure. Put the Extremii in it and use them full-range. When time and budget or what ever permit, add the WR125 with the woffer and mid-woffer crossovers. Later add the twetter with its crossover. will not save any money that way...
Pete, I'm thinking about building a subwoofer to use for about 50% Music/50% HT. How did your TL sub turn out? Would you use the same design again? Thanks, Elza
